My Nobler ARF crashed because of the pilot. It flew great until that.sdjjadk wrote:Sorry to hear about the crashes.
I'm kind of glad I haven't flow mine yet. So do the Nobler arf's just go nose in without warning? Or just when the engine quits? Is it a CG problem or incidence problem? Is there is anything I can do to prevent it from nosing in?
This is my first T/F Nobler arf and the last Nobler I flew was a kit built Junior back in the 80's but I seem to remember it having no bad tendencies what so ever.

Re: Dabbling in the Darkside (other nitro engines)
Do you have any idea why it kept sinking? Control rod bowing, maybe? Anyway, I'm glad it's okay. Other than scraping some of the Pretty off, they usually hold up pretty well. I should know, I've pancaked the SS about three times, under shooting inside loops.

Re: Dabbling in the Darkside (other nitro engines)
I had never seen a Nobler in real life until Wayne brought his to the field a couple of week ago. Someone anonymously left an ARF at his club and nobody wanted it. After a meeting it was in his truck bed, so he took it home. All the control surfaces were glued and immobile. He fixed it up and put a Brodak .40 in it, and the thing flies great. It's rock solid and on track. I can't hold my SS as level in flat laps as he flies the Nobler. The landing glide is at least a full lap and no bounce on touchdown at all. But I don't know how much of that is the plane and how much is him. Last week the weeds in the field were slapping over the LE and punched holes all in the top of the wing covering. Yesterday, the blue wing had little red dots all over it like acne... or bullet holes. Ha, that's what he should have patched it with, bullet hole stickers.sdjjadk wrote:Sorry to hear about the crashes.

Phil, I feel your disappointment. My second flight of the SS was off a stooge in tall weeds. They grabbed the lines and the plane took off and flew over my head and nosed in softly, breaking my defective Dural LG and brand new Top Flite 10x4 woody. All that trouble to set up to fly, and I'm already packing to go home. Grrrr!

Re: Dabbling in the Darkside (other nitro engines)
I have no idea. I put a couple of flights on it today and it flew great. I even let a friend fly it who hasn't flown C/L in over 20 years and he had no problem controlling it either.RknRusty wrote:Do you have any idea why it kept sinking? Control rod bowing, maybe?

Funny wind rolloff, maybe. Ate you near trees or a building? In the churchyard I do 1/2A in, the wind rolls off the rooftops and there's one area that will pancake it every time you fly a flat lap through it. I always fly high through that quarter of the circle.

Re: Dabbling in the Darkside (other nitro engines)
At least I got the engine running this time! Last time I couldn't get fuel into it, even though I flushed the tank a few weeks prior.
I am getting taller wheels, either that or I need to take off the existing landing gear and put on taller.
I also think some cleats on the first board for my stooge might be a good idea, and maybe another board or 3 so I have 10 ft or more roll space.

Re: Dabbling in the Darkside (other nitro engines)
Shawn they fly fine, they are nose heavy out of the box. In my case the engine was set too lean and when inverted it leaned even more causing the engine to seize.sdjjadk wrote:Sorry to hear about the crashes.

Seize or stop? Inverted flight is no reason for an engine to seize.
If so, I'd stop flying inverted!

Seized. Not my plane nor did I set the needle. I was asked to fly it to test how it flew. Last time I do that. I hate breaking folks planes.

Did you do a post mortum on the seized engine yet?
Usually seized engines were run on fuel without proper lubrication OR were very tired to begin with. That's my experience anyway.

Re: Dabbling in the Darkside (other nitro engines)
No, sure didn't Dave, I was told it was fine though. Not sure of the fuel used, but the owner is not new to the game. My guess is a lean setting coupled with improper tank height/pickup.

I had to cut a small patch of covering and add a 1/2 oz. of weight inside the tail of the fuse to get it to balance with my .40 LA

Post Mortem:
The Nobler flew well. Balanced fine. Tank position is not able to be altered. Engine is right-side-up when plane is inverted, but perhaps cowled too tightly- resulting in overheating from lack of airflow.![Dabbling in the Darkside (other nitro engines) - Page 2 100_1310](https://i.servimg.com/u/f72/18/21/81/32/100_1310.jpg)

Re: Dabbling in the Darkside (other nitro engines)
Nice illustration. But it looks like a wingover started on the wrong side of the wind. You gotta have a tailwind at the top to help push it on over. But how did you pull up like that a quarter lap after the engine died? Or were you just trying to flip it over to avoid an inverted landing?GUS THE I.A. wrote:

Re: Dabbling in the Darkside (other nitro engines)
Ask Ron why he did not just step off the center, to land inverted in the grass, as is S.O.P. for this situation. A vertical fin repair beats a toast airplane, any day.

Ouch!
good drawing.
No need to ask, I'll tell you. Lack of experience on my part. Still feel bad about it.

Re: Dabbling in the Darkside (other nitro engines)
I keep reading that exit ventilation is more important than entry ventilation for cooling purposes. Apparently if there is not enough space for hot air to exit overheating is more likely.
"Ouch" indeed.

Re: Dabbling in the Darkside (other nitro engines)
Yeah, Phil, I guess hot air is bigger than cold air. There is some rule of thumb multiple they use; exit area must be x times inlet area.pkrankow wrote:I keep reading that exit ventilation is more important than entry ventilation for cooling purposes.

I fly profiles, so I'm always cool.

Re: Dabbling in the Darkside (other nitro engines)
Just to give you guys a breakdown....that pic Gus drew is of my flight with his Nobler in Wichita KS. It seized up while going inverted and as the picture shows I tried to save it from an inverted landing by flipping it into the wind which results in slack lines and nosing in. My mistake.
This thread really went off track
The ARF TopFlite Nobler flies very well. There is some construction problems with it though.

Re: Dabbling in the Darkside (other nitro engines)
Accurate drawing even showing the slack lines. Sorry I Had to point that out. I have the figure 9 down path as well on my RC planes. I keep a small shovel handy to dig the engines out of the dirt.
